lNTERMEDlAIE-LlNE-SPACINGDEVICE FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 716,215, dated December9 Application filed March 7,1901.

To otZZ whom it may concern:

Be it known that I, JAM S A. GARLAND, Jr., a citizen of the UnitedStates, residing at Hamilton, in the county of Essex and State ofMassachusetts, have invented a new and useful Improvement inIntermediate-Line- Spacing Devices for Type -Writing Machines, of whichthe following is a specification.

The object of myinvention is to provide an intermediate-line-spaeingdevice for typewriting machines of the class employing a paper-roll orpaper cylinder, of which? the Remington machine is a well-known example.

It is often desired to print letters or figures at some intermediatepoint between two nor mal lines of printing-as, for example, in

writing exponents. To accomplish this Without the aid of anintermediate-line-spacing device itis necessary for the operator to turnthe paper-cylinder by hand the desired distance from the normal line,hold the cylinder while he prints the desired letters or figures, andthen turn the paper-cylinder back toits original position for continuingthe printing upon the normal line, or to slip the paper upon thepaper-cylinder, print the intermediately-spaced characters, and thenslip it back. Such manual adjustment necessarily causes much lossoftime, and, furthermore, the distance of the points at which the.intermediately-spaced characters are to be placed from the normal linecan only bekept approximately constant by the exercise of the greatestcare and attention,and consequently the' work usually presents a more orless uneven possible in writing, and it renders the intermediate linesuniform and fixed at a prede termined distance from the normal line,which distance I have made provision to regulate, as desired.

Serial No. 50,183- (No model.)

embodiment of my invention applied to a No. 6 Remington type-writingmachine. Only those portions of the machine with which my invention isimmediately concerned are shown in the drawings, as the machine as awhole is too Well-known to require illustration or detailed description.It is, however, obvious that my invention is adapted to be applied toany type-writing machine which employs a paper-cylinder adapted forspacing the lines.

In the drawings, Figure 1 is a plan view of one end of thepaper-carriage and paper-cylinder and of my intermediate-line-spacingdevice attached thereto. Fig. 2 is a sectional View of thepaper-carriage, taken through the line X X of Fig. 1, showing inelevation my intermediate-line-spacin g device in its normal orinoperative position and the end of the paper-cylinder. Fig. 3 shows thesame View of the parts as Fig. 2, except that the linespacing device isshown in its operative position. Fig. 4 shows in, plan View the platenand its carriage, with the usual line-spacing mechanism at one end andthe intermediateline-spacing mechanism at the other.

The same parts are indicated by the same letters of reference in all thefigures.

A represents the frame of the paper-carriage, and B the paper-roll orpaper-cylinder. Concentric with the paper-cylinder B and mounted on theaxis 0 of the paper-cylinder and securely keyed thereto or to thecylinder is the cog-wheel-or spur-wheel D. In the .plane, ofthespur-wheel D is the movable arm E, which may be pivoted at the rod a,which usually supports the index adjacent to the paper-roll or at anyconvenient point. This arm E is curved downward,so as to pass: under thespur-wheel D, as is shown in Figs. 2 and It is provided at its outer'endwith the lever or key E. In its normalror inoperative position the arm Ebears against the bottom of the paper-carriage frame A, and the:key Emay be used as the handle'by which the paper-carriage is elevated forinspecting the writing. Integral with the arm E and in close proximityto and slightly above the center of the spur-wheel D is the clutch F,adapted to engage with the cogs of the spur-Wheel. The tension-spring S,attached to the frame A of the paper-carriage and to the arm E,no.rmallyholds the clutch F out of engagement with the spur-wheel D. Consequentlywhen my intermediate-line-spacing device is not in use it in no wayinterferes with the usual linespacing mechanism of the machine. The armE is provided with the finger or stop G, which coming into contact withthe frame A of the paper-carriage limits the downward movement of thearmE. The length of such downward movement may be governed by using theset-screw H in the stop G. The number of cogs on the spur-wheel Dcorresponds to the number of cogs on the spur-wheel at the opposite endof the paper-cylinder, which forms a part of the ordinary line-spacingmechanism of the machine, so that in any position which thepaper-cylinder may take under the control of the line-spacing mechanismof the machine a cog of the spur-wheel D will be brought into the properrelative position to the clutch F.

The operation of my device is as follows:

The operator, desiring to print upon a line intermediate between thenormal lines of print, depresses the arm E by means of the key or leverE, overcoming the tension of spring S, until the movement is arrested bythe stop G or the set-screw H, when the latter is used. The initialmovement of the arm E brings the clutch into engagement with thespur-wheel D, and the continued movement rotates the spur-wheel and thepaper-cylinder the distance desired for the intermediate linespacing.Uponreleasingthe keyE'thespring S at once returns the arm E to itsnormal position against the under side of the frame A, and the clutch F,bearing upon the cog of the spur-wheel D nextaboveit, returns thepapercylinder to its original position and withdraws from engagementwith the spur-wheel, leaving the paper-cylinder free to rotate under thecontrol of the ordinary line-spacing mechanism of the machine.

The ordinary line-spacing device is indicated generally at "N, Fig. 4,wherein n is the operating-handle, and n the clutch mechanism.

I do not intend to limit myself to the spe cific form of clutchdescribed above, as it is obvious that a friction-clutch or other formof clutch adapted to engage the paper-cylinder by an initial movementand to rotate the same independently of the line-spacing mechanism ofthe machine is within my invention.

What I claim, and desire to soon re b y Letters Patent, is-

1. An intermediate-line-spacing device for type-writing machines,comprising a clutch normally out of engagement with the papercylinder,means for engaging the clutch with the paper-cylinder and for rotatingthe same independently of the line-spacing mechanism of the machine, andmeans for automatically returning the paper-cylinder to its originalposition under the influence of the clutch.

2. An intermediate-line-spacing device for type-writing machines,comprising a spurwheel concentric with and secured to the paper-cylinderand a clutch normally out of engagement with said spur-wheel and adaptedto be moved into engagement with said spurwheel and to rotate thepaper-cylinder a predetermined distance independently of theline-spacing mechanism of the machine and means for automaticallyreturning the papercylinderto its initial position under the influenceof the clutch.

' 3. An intermediate-1ine-spacing device for type-writing machines,comprising a spurwheel concentric with and secured to thepaper-cylinder, and a clutch normally out of engagement with saidspur-wheel andadapted to be moved into engagement with said spurwheeland to rotate the paper-cylinder a predetermined distance independentlyof the line-spacing mechanism of the machine and adjustable means forlimiting in scope the movement of the cylinder under the influence ofthe clutch to a distance less than a normal line-space, and means forautomatically returning the paper-cylinder to its original position.

4. An intermediate-line-spacing device for type writing machinescomprising a spurwheel concentric with and secured to the cylinder, anda clutch pivoted eccentrically with said spur-wheel normally out ofengagement with said spur-wheel and adapted to be moved into engagementwith said spur-wheel and to rotate the paper-cylinder a predetermineddistance independently of the line-spacing mechanism of the machine, andmeans for automatically returning the papercylinder to its initialposition under the influence of the clutch.

5.
